Egyptian authorities say new radar scans have failed to detect any hidden chambers in the tomb of ancient boy-king Tutankhamen. Now, the most conclusive study to date has weighed in on the controversial theory.

The revelation contradicts the proposition of British Egyptologist, Nicolas Reeves, made in 2015, that Queen Nefertiti's tomb could be concealed behind wall paintings in the king's chamber. Has this ended the speculation that there remains to be discovered another tomb alongside that of Tutankhamun's?

Researchers with Italy's Turin Polytechnic University have found no evidence of the existence of any secret chamber behind King Tutankhamun's burial chamber, Egypt's Antiquities Ministry said Sunday.

Following these big claims, three separate archaeological teams have beamed radar surveys at the tomb in the hopes of uncovering the truth.

"It is maybe a little bit disappointing that there is nothing behind the walls of Tutankhamun's tomb", said Francesco Porcelli, head of the research team.

They believe the painted plaster walls that cover the limestone may have conducted the radar in places, instead of absorbing it.

"It is concluded, with a very high degree of confidence, that the hypothesis concerning the existence of hidden chambers or corridors adjacent to Tutankhamun's..."

However, this new research showed no such indication of any suspicious walls, nor any large empty voids lurking behind them.

On Saturday, Tutankhamun's sixth and last historic military chariot was moved from a military museum in Cairo to the under-construction Grand Egyptian Museum near the Pyramid complex in Giza, which is scheduled to display about 4,500 new and unique pieces of the boy king after its opening later in 2018.

Egyptian authorities chose to stop looking for hidden premises in the tomb of Pharaoh Tutankhamun. His linen-wrapped mummy was buried in a lavish golden sarcophagus, and the tomb, discovered by British archaeologist Howard Carter in 1922, is the most famous of all the burial sites in Egypt's Valley of the Kings and the source of ongoing fascination, myths and legends.
